New Jaguar XF Diesel S

The new XF V6 Diesel S combines superb performance with energy consumption. From 0 to 100 km / h in 6.4 seconds and 250 km / h maximum speed, but an average consumption of 6.8 litres/100 km.

Since its launch, which took place last year, the XF has been recognized as the result of extraordinary new direction of Jaguar design. E 'soon became evident that this was a car in which the pleasure of driving exceeds the expectations created by its beautiful line. Today, the new XF Diesel S raises the driving pleasure to new levels, shifting the balance further while maintaining the core values of sophistication and luxury sport sedans of the XF.

Based on the considerable experience gained in designing the 2.7-liter engine, new diesel 3.0-liter AJ-V6D Gen III show that it is possible to ensure greater performance while reducing consumption and emissions of CO2. XF in the new engine produces 10 percent less CO2 than the 2.7D, while the power was increased by 33 percent as Diesel S. In addition to reducing CO2 emissions, the new 3.0-liter engines meet the Euro 5 legislation which comes into force in early 2011. These significant performance gains are obtained with an average consumption in the combined cycle of 6.8 litres/100 km for both models, an improvement of more than 10 percent compared with the 2.7 liter engine.

A key feature of the new engine is the exclusive system of parallel sequential turbochargers, the first of its kind to be installed in a motor V worldwide. With high torque across the range of engine speeds, improved responsiveness of the throttle and low emissions of CO2, the two turbochargers run in a sequential order to ensure a unique and the best pair of category at low revs, ensuring enormous increase of power at rates higher. In most everyday situations, including driving on the motorway, you use a turbocharger primary variable geometry reactive, while the smaller secondary turbocharger geometry sets is idle, saving energy and improving efficiency.

When the engine turns over 2800 per minute, the secondary turbo intervenes within 300 milliseconds, going to increase fluid and continuous power of the engine without any perceptible delay, nor any drop in performance. To drive a turbo pressure should be from the exhaust that creates pumping losses in the engine, increasing fuel consumption. To remedy this, valves controlled by the engine management system isolating the secondary turbocharger from the exhaust stream that suction from the engine when not needed.
